So I'm gonna defend for Sakura. Yes Sakura Haruno. I don't know why she was hated much though. In fact, she was one of the characters that I hold deep respect for.
In the beginning, she was just that annoying kid who had crush on Sasuke. As the team form bond strengthen in them.
And as we went on, she developed. She tried to deal with the fact Sasuke betrayed them, even though she still shed tears for him, the develop of her through that time was pacing really good.
And another thing we can't forget is how she comes face to face with Sasuke with no doubt to bring him back to them as team. She knew she could never ask Sasuke to return her affection, but still, it was really cool for her to still had faith in him, fight him at all cost, strike him with no doubt.
And in the end, she end up together with Sasuke. I ship NaruSasu, but still, seeing the development of Sakura is really interesting. In the end, I can still say she deserve to end with him, even though I ship NaruSasu.
